摘要： A system and method determines a unique performance benchmark for specific computer object code for a particular microprocessor. By generating multiple unique benchmarks for a single, same code module on multiple different processors, the method determines which processor is optimal for the code module. By generating for a single designated processor a performance benchmark for each code modules of multiple modules, where the multiple modules have a same/similar functionality but variations in detailed code or algorithms, the system and method identifies code variation(s) which is/are optimal for the single designated processor. The system and method may entail first extracting selected features of object code (as actually executed) into a code profile, and then generating the performance benchmark based on the code profile and in machine-level timing data for the selected microprocessor. In this way, code security is achieved by fire-walling the object code from the second stage of the method.
